I'm not sure on where to post this, so i've posted it in a couple of places and if this isn't the right place, i apologise.
Basically, i tend to find that the battery for my Blackberry 9300 doesn't last as long as my previous phones, it struggles to last a day at college..
Tomorrow, i'm leaving 'sunny' yorkshire to go to london to watch Huddersfield Town away at charlton and i'll be leaving my house at 6.30am and returning about 10pm, so i doubt my battery will last..
My sister has an old blackberry she doesn't use anymore, a 8520. If i was to charge the battery from this phone, would i be able to put it in my 9300 and would it work?
